A square QR code contains 40×40 tiny squares (pixels) where each tiny square represents a 0 or a 1. Calculate how many bytes of data can be stored on the QR code​

Answer:

Explanation:

QR Codes are made of multiple rows and columns. The combination of these rows and columns makes a grid of modules (squares). There can be a maximum of 177 rows and 177 columns which means the maximum possible number of modules is 31,329. With the eye, these are just small squares and mean very little, but the exact arrangement of those modules allows the QR Code to encode its data. This means that, unlike traditional barcodes which are 1 dimensional and use 1 row of lines, QR Codes use 2 dimensions which allows them to store a lot more data in the same area of space.
